640 Leaky Radiator

Got a leak near the top of our 640 radiator (w/shroud) at the seam where the reservoir joins the radiator itself. It's the orginal radiator I'm assuming. We bought the tractor in 1986.

Would you all suggest I get a new radiator or take the old one to a radiator repair shop and have it refurbished?

Would the new radiator need a shroud?

What other helpful hints do I need to know to remove the radiator. I'm going to take the hood off to allow me access to the radiator.

Thanks in advance,
John

If you want to try to fix it yourself. Drain/remove radiator. Get a propane touch, some solder, muriatic acid and wire brush. Clean area with brush and then clean with acid. Heat seam just enough to meld solder. The solder will be pulled into the joint and seal it. Don’t worry about breaking/damaging anything, it’s broke/damaged already. I repaired the radiator on my 801 leaking in the same place this past summer .

If you need a quick in place fix, I just patched a tube that had a 1/4" hole in the front of it. Used some J B Weld after cleaning area with a rotary brush in a Dremmel too. With the 4# cap it's still holding after 2 weeks.

Happy New Year

If your radiator is orginal I would try to keep it at all cost. It is made much better than the china junk of today. The shop will know once they boil it out if it can be repaired or needs replacing.

If you look at the top of the radiator you should see a date code if it is the orginal one.

Every radiator needs a shroud.

A good radiator shop can probably fix it. Should not need a replacement unless you have not done proper maintenance. An annual (or at least every 2 years) coolant change useing 50-50 or better mix of quality antifreeze and distilled water is proper maintenance. As to removal, follow the Ford Repair Manual, which I assume you have since you have owned the tractor fo 21 years. Tom
